BRICK-MACHINE.

Specification forming part of Letters Patent No. 213505, dated July l2,186i.

T) atl whom it may concern:

Be it known that I, FREEMAN JAcoBm, of-

the city of Albany, county ot' Albany, and State ot' New York, haveinvented a new and Improved Brick-Making Machine; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, making a partof this specification, in which- Figure l is a side elevation of myimproved machine. Fig. 2 is an end view of the same. Fig. 3 is avertical longitudinal section through the entire machine, and Fi 0. 4 isa transverse section taken in the vertical plane indicated by red line xx in Fig. 3. v

Similar letters of reference indicate corresponding parts in the severalfigures.

The nature ot' my invention consists in arranging within a suitable boxor receptacle a rotating` conveyer which will operate as such, and alsoas a disintegrator, and force the clay into a chamber, where it is actedupon by a revolving beater and feeder and forced into a molding-box,from whence the clay is discharged under pressure by means of a followerinto molds adapted for receiving it and giving the required shape to it,as will be hereinafter described.

My invention also consists in a new and improved contrivance forgoverning the pressure of the follower and timing the movements of thesame according to the various conditions of the clay used in themanufacture of bricks, as will be hereinafter described.

My invention further consists in a reciprocating pusher-incombinationwith a molding-` box, and a platform arranged beneath saidbox for supporting the movable molds which receive the clay forced outof thc moldingbox, as will be hereinafter described.

rlo enable others skilled in the art to make and use my invention, Iwill describe its construction and operation.

In thel accompanying drawings, A represents the frame-work ot' mymachine, which is constructed of such strength and capacity as willadapt it for receiving` and supporting` the several parts of themachine, which are employed for preparing the clay and forcing it intothe brick-molds.

B represents a horizontal clay-box, which is open at top and closed atits sides, bottom,

and one end, which end opens into a vertical receptacle, B.

C represents a horizontal and longitudinal shaft, which has its endbearings in the frame A, and which is rotated by means of a beltwheel,a, that is driven by any suitable prime motor. This shaft C is providedat suitable intervals along its length with tins or knives b b b, andalso with segmental plates b b', arranged obiquely to the axis'of theirshaft. The tins or knives operate in conjunction with vertical and iixedknives b2, projecting from the bottom of the horizontal box B, anddisintegrate the clay, while the oblique wings or propellers b b forcethe clay toward and into the chamberB. The conveyer-sh'aft G carries onits end nearest the box B', and outside ot' this box, a pinionspur-wheel, c, which engages with and drives a spur-wheel, c', which iskeyed on the end ot' a short shaft, C', arranged beneath that portion oftheshaft C, which extends across the box B. To this shaft C radial armsc c are secured, carrying on their ends plates c c', which operate uponthe clay as beaters and stirrers and greatly assist in thedisintegration of the clay alter it leaves the horizontal box B, andpreparatory to its entering a small box, D.

The box D, which l term a press-box, rcceives the clay in a conditionfor working into bricks through an opening, f, through the side ot' thebox B', and as the. clay is compressed into this press-box it is forcedout through a number ot'quadrangular holcs,f, in the bottom ot' said boxby means of a plunger, E, which is elevated and depressed, as will behereinafter described. The openings through the bottom of the press-boxcorrespond in number to the chambers in a mold-box, which l haverepresented in red lines, Fig. 4, said chambers being the molds intowhich the clay is shaped. I have represented only one ot' the mold-boxesused in my machine, as they are all of an equal size and contain anequal number of chambers. They may be mounted on wheels or not, and whenused two are placed on the adjustable or swinging platform F one beingarranged directly under the press-box D and the other directly behindit, to be forced up in the position of the first by means ot' afollower, G, when this one is lled,.as will be hereinafter described.The

edges of the openings through the press-box D may be beveled downward,as shown in Fig. 4, so that when the filled chambers of the mold-boxesare moved away from the machine to be emptied these edges will leavetheupper surfaces of the bricks smooth and level.

The plungerE may be furnished with a vertical plate projecting up fromthat edge nearest the box B', which pla-te will close the opening fshould the plunger descend below it and prevent any of the clay frombeing forced over this plunger.

The plunger rod 7L passes up through a bracket guide, IL', and carrieson its upper end a hollow guide-box, h2. This box receives in its upperend the rod h3, that is connected by links t' to one end of aworking-beam, H. That end of rod h3 which enters the upper end of thebox h2 has a pin,j, passing transversely through it, and also throughvertical slots in each side of said box, and through the opposite sidesof the box h2 a number of holes are made, one above the other, for thepurpose of receiving the pin j' By this arrangement it will be seen thatthe rod h3 is allowed to descend a certain distance before it will actupon the plunger to depress it, which distance can be regulated byadjusting the pin j'; and, then again, when the rod It8 starts upwardsit will move through a corresponding space before the pin j is broughtinto operation to elevate the follower. This vintermittent movement ofthe plunger gives time for the follower G to move one of the emptymold-boxes up to its place under the press-box andy then to recede againa sufficient distance to admit of another mold-box being introducedbehind the iirst.

rlhe working-beam H is supported on top of the machine, and has itsfulcrum in pillowblocks k lr. The long arm of this beam is connected bymeans of a pitman, 7c', to a crank, I, which is on a shaft, U2, thatreceives its motion from the main shaft U through the medium ofspur-wheels c c c2. This shaft C2 carries a crank-arm, a, having awrist-pin, a', projecting from it and entering an oblong slot in avibrating arm, p, which is pivoted to an overhanging bracket, p'. Thelower end of the arm p enters a slot formed in a projecting portion ofthe follower-plate G', which plate is guided by means of two fixed jaws,which are secured to the bottom ofthe box B', as shown in Fig. 3, and onthe inner end ofthe plate G', the T-head G which I call the follower,"is secured.

The table or platform F is arranged beneath the follower G and press-boxD, and hinged at y to the frame A at one end, and suppoited at or nearthe other end by togglelevers s s, which are used to elevate or de.

press the platform F. It is important to employ a table which is capableof being adjusted up to and from the prcssbox, inasmuch as the moldboxes should be forced up closely against the bottom of the press-boxand held in this condition, the passage of the boxes under it.

Having thus described the construction and operation ofthe individualparts of my machine, I will briefly describe the operation of makingbricks in this machine: The cla-y is introduced into the horizontal boxB, where it is disintegrated and forced forward into the box B', andthence compressed into the pressbox D. During the operation of fillingthe machine the pin J' may be removed and the plungerE disengaged fromthe working-beam H. When the box D is filled and the plunger properlyconnected to the working-beam, this plunger descends and forces out ofsaid boxr the clay and presses it into the mold-box which had beenpreviously arranged under D. During the descent of the plunger E thefollower recedes and allows a mold-box to be introduced between it andthe mold-box which is being filled. Vhen the plunger rises, the followerforces the filled box out ofits place and also forces the empty boxunder the press-box and then returns to allow another empty box to beintroduced behind the former.

WhatI claim as my invention,and desire to secure by Letters Patent, is-

l. The intermediate chamber, B', forming a vertical continuation of thehorizontal or nearly horizontal chamber B, and also communicating withthe press-box D, substantially in the manner and for the purposedescribed.

' 2. The combination ofthe rotary discharger C' e e', or its equivalent,with the intermediatechamber, B', substantially as and for the purposeset forth.

3. The combination of the three boxes or chambers B B' and D,communicating with each other, with the conveyer (l, and revolvingdischarger C' all constructed and operating substantially as and for thepurpose set forth.

4. The adjustable hinged table F, arranged beneath the press-box D andclaybox B', substantially as and for the purpose set forth.

' 5. The combination ofthe reciprocating follower G, a platform, F, andpress-box D, constructed and operating substantially as described.

Witness my hand in matter of my application for a patent for an improvedbrick-machine.
